The object of my invention is to facilitate the manufacture of coke by dispensing with the large amount of manual labor which is z5 required in connection with the means heretofore commonly employed in the coking of coal.

My invention comprises a stationary coking-hearth, an oven movable from the hearth 3o to a iioor or platform, and means for lowering the platform or floor, so as to leave the charge of coke free from the oven and upon the ioor or platform. I believe this combination of the coking-hearth, the laterallymovable coke-oven, and the vertically-movture built within a circular metal shell 3.

The oven is supported at four or more points by brackets 5, which rest upon and within a truck-frame el of metal beams. The truckframe itself is mounted upon wheels 6, which 5o run upon a track 7, leading over the cokinghearth 8. For the purpose of enabling the oven to be raised somewhat in the truckframe I provide the latter with lifting mechanism, which may consist of levers 9', Figs. 5 and 6, having their fulcrums at the journals 9 and bearing at l0 against the beamsof the truck-frame and at Il against the heads of adjusting-bolts 12, which fit in threaded nuts 13 on the brackets 5, this arrangement being duplicated on the opposite sides of the oven. By turning the bolts l2 the outer ends of the levers at l0 are raised, and the oven is lifted relatively to the wheels 6. It will be understood that other means for raising and lowering the oven on the cokinghearth may be substituted.

In front of a line of movable ovens constructed as above described is a track 14., on which travels a car l5, carrying the platform 1G, above mentioned. This platform, which I showin the drawings as consisting of a grid or grating, is adapted to be moved within upright guide-posts 17 on the car 15 by suitable lifting mechanism, which may consist of chains 18, passing over pulleys 19 to a power-driven drum 20. The car 15 has rails 2l, adapted to register with the rails 7 of the coking-hearth and to afford a track on which the coke-oven may be moved over the platform 16. For the purpose of quenching the coke I may provide a car with a quenchingtank 22, adapted to contain water and situated below the normal level of the platform. I may employ a supply-tank 23, from which water may be admitted into the tank 22, and a pump 24, by which the surplus water may be returned from the tank 22 to the tank 23, an intermediate screen 25 being employed to separate the ashes and other fragments from the water.

I employ devices for discharging the coke into the cars or other receptacle into which it is to be loaded and prefer to locate them above the level of the coking-hearth. I find it convenient to employ a mechanism which will serve the double purpose of pushing the coke from the platform and drawing the oven over the platform. 26 26 are endless chains which pass over pulleys 27 and driven pulleys 28. Attached to these chains is a pusher-bar 29, supported on beams 30, and the chains have also a link or links 3l, adapted to be detachably connected at 32 with the frame of the oven.

ICO

'Ihe operation of the device constructed' as described above is as follows: The oven being in position on the coking-hearth 8, as shown by full lines in Fig. l, and a charge of coal having been coked therein, if it is desired to discharge the contents of the oven the adjusting-bolts 12 are operated, so as'to raise the oven slightly above the level of the coking-hearth, and the car 15 having previously been brought into the position shown in Fig. 1 the links 31 are attached to the oven and the chain 26 started in motion, whereupon the oven will be drawn into the position shown by dotted lines. Thel coked charge is thus drawn by the oven over the cokinghearth and upon the platform 16. The platform is then lowered by operation of the drum 2O and the chains 18 and is lowered into the tank 22. Water is then admitted into the tank and the coke is quenched. Meanwhile by reversing the motion of the chain 26 the oven, now freed from the coke, is pushed back onto the coking-hearth 8, and the links 31 are then detached therefrom. Then by operation of the chains 18 the platform 16 is raised to the level of the pusher 29, the chain 26 is started into motion, and the pusher is drawn along the platform 16, pushing the coke before it and discharging it into the car 34 or other place where it is to be received or stored. The car 15 may then be moved to another oven of the line. The discharged oven having been recharged with coke is lowered upon the coking-floor by a reverse operation of the bolts 12, a packing of asbestos fiber or luting of clay being first interposed between the edge of the oven and the floor in order to eX- clude the air.

In Fig 4 I show a modified form of my apparatus in which the oven 2 is raised while resting on rails 2l', which are provided with lifting-chains 33,which are wound upon drums 35. The weight of the rails 21' and the oven 2 is counterweighted, as shown, so that very little power is required to lift the oven from the platform 16. This platform 16/ is not movable up and down, but is movable upon the tracks 36, mounted on the car 15. The operation of this form of my apparatus is as follows: The oven 2 is moved from the hearth 8 until it rests upon the rails 21 and over the platform 16', the top of the coking-hearth and the top of the platform being at the same level. The drums 35 are then revolved and the oven is lifted to the desired height, leaving the body of coke upon the platform 16 free from the oven, after which it may be moved to the desired point for quenching. The oven is then lowered and placed in position upon the hearth. A fresh charge of coal being supplied to the oven, the coking operation again proceeds.

Myinvention enables me to operate a cokeoven in much less time and with much less Ilabor than heretofore, and is therefore efficient in reducing greatly the cost of manufacture.

It will be understood by those skilled in the art that the apparatus may be varied in many ways within the principle of my invention, since What I claim is- 1.
